14.6.6.8GENERAL INFORMATION:

A.Any
license issued pursuant to the CILA and Title 14 NMAC authorizes contracting in
the activities covered by the classification(s) of the issued license
only.Work performed outside that scope
constitutes a violation of the act and these rules and constitutes grounds for
disciplinary action.

B.Bidding as a prime contractor:

(1)A validly licensed person may bid and contract as the prime
contractor of a project only if the major portion of the work, based on dollar
amount, is authorized by the classification of the prime contractor’s
license.Any work outside the scope of the
prime contractor’s license classification(s) must be subcontracted.

(2)A GB-98 contractor may bid and contract and contract as the
prime contractor of a project that involves work authorized by the GB-98
license certification, regardless of the percentage of work in the
mechanical/plumbing or electrical trades.The work outside the scope of the prime contractor’s license
classification(s) must be subcontracted to an entity validly licensed in the
appropriate classification(s).

(3)A
GB-98 contactor may not bid and contract as the prime contractor of an entire
project if the major portion of the work to be performed, based on dollar
amount, is covered by the scope of any GA or any of the following GF
classifications:GF-1, GF-2, GF-3, GF-4,
GF-6, GF-8, and GF-9.

C.Any work subcontracted by a prime contractor must be
performed by an entity that is validly licensed in the classification(s) of the
work that is to be subcontracted.

D.Any
license issued in a classification that is subsequently discontinued, shall be
renewed under that classification until the license becomes invalid.When a license issued in a discontinued
classification becomes invalid, the entity that held that license will be
required to apply for a new license in the appropriate classification in effect
at the time of the application in order to be validly licensed to engage in
contracting in the state of New Mexico.Such an applicant will be required to satisfy all requirements for
licensure as provided in the CILA and Title 14 NMAC.
